Chapter 5. Making Use of New APIs to Improve Your Code

In the previous lessons, we talked about possible ways to improve the performance of your Java application--from using the new command and monitoring tools to adding multithreading and introducing reactive programming and even to radically re-architecting your current solution into an unruly and flexible bunch of small independent deployment units and microservices. Without knowing your particular situation, there is no way for us to guess which of the provided recommendations can be helpful to you. That's why, in this lesson, we will describe a few recent additions to the JDK that can be helpful to you too. As we mentioned in the previous lesson, the gain in performance and overall code improvement does not always require us to radically redesign it. Small incremental changes can sometimes bring more significant improvements than we could have expected.

To bring back our analogy of a pyramid building, instead of trying to change the...
